Embodiment 1
[0012] Embodiment 1: with reference to attached figure 1 . A jump-type electronic fence system, including an electronic fence 2 and a plurality of alloy wires in the electronic fence 2 are arranged at intervals from top to bottom, and the two ends of the plurality of alloy wires 2 in the electronic fence 2 are in static contact with the starting intermediate relay 3 respectively The point is connected to the moving contact of the end intermediate relay 1, and the static contact of the end intermediate relay 1 is matched with the static contact of the starting end intermediate relay 3 to form a jump switch of a pulse output circuit of multiple alloy wires. When there are four alloy wires in the electronic fence 2, the jump switch of the pulse output circuit formed by the four alloy wires 2 in the electronic fence 2 is that the first alloy wire goes out, the third alloy wire enters, and the second alloy wire enters. Out, the fourth alloy wire in. That is, the output terminals ...
Embodiment 2
[0013] Embodiment 2: with reference to attached figure 2 . On the basis of embodiment 1, when there are six alloy wires in the electronic fence 2, the pulse output circuit jump switch formed by the six alloy wires 2 in the electronic fence 2 is the output of the first alloy wire, the third and the fifth The first alloy wire enters, the second alloy wire exits, and the fourth and sixth alloy wires enter; when the jump occurs, the first alloy wire exits, the second and fifth alloy wires enter; the third alloy wire enters The wire goes out, the fourth and sixth alloy wires go in.
Embodiment 3
[0014] Embodiment 3: on the basis of embodiment 1 or 2, a kind of cyclic jump detection method of the jump type electronic fence system, set the timing time of opening and closing jump of adjustable time interval electronic timer 5 as required; When the electronic fence 2 is in the starting working state, the start-end intermediate relay 3 and the end intermediate relay 1 connected to the electronic fence 2 are in a normally closed state, and one end of the switching contact and the jumping static contact are in a normally closed state. The wires are arranged in order from top to bottom to form an odd-numbered alloy wire switch circuit and an even-numbered alloy wire switch circuit, or a switch circuit composed of an odd-numbered alloy wire and a switch circuit composed of an even-numbered alloy wire; when the starting intermediate relay 3 and the terminal intermediate relay 1. When receiving the jump signal of the adjustable time interval electronic timer 5, the moving contact...
